<p>A structural panel (10, 12, 30, 50, 70) comprises a metal and paper composit e in which the metal outer skins (22, 32, 40, 52, 60) have a minimum thickness of 0.005 in. (1.0 mm) exceeding foils and a preferred maximum thickness of 0.012 in. (0.3 mm) while the paper core (20, 36, 56) ranges between 0.01 in. (0.2 mm) and 0.05 in. (1.3 mm). The panel is a stiff, lightweight substitute for thicker metals and may replace light metal sheets such as aluminum with a composite in which the metal skins comprise sheets from heavier metals such as steel. The paper core (20, 36, 56) is adhesively bonded to the metal skins a nd may have openings (62) to create paths for adhesive bridges (64) between the metal skins (22, 32, 40, 52, 60) to minimize failure caused by buckling.</SD OAB></p> |
